LUDWIG TOPF, OF EEFURT, GERMANY.

APPARATUS FOR PRODUCING. AND CONTROLLING MOISTENED AIR DRUMS. I I I Toall whom it may concern Be it known that I, LUDWIG Torr, a citizen ofthe German Empire, residing at Erfurt, in the Kingdom. of Prussia,Empire of Germany, have invented certain new and useful Improvements inApparatus for Producing and Controlling Moistened Air in Malting-Drums;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The present invention relates to an improved apparatus for imparting aproper degree of moisture to the air used in malting drums, and withthis object in view the invention consists in a particular arrangementof moistening apparatus positioned in close proximity to separating anddistributing elements.

The invention is illustrated in the accompanying drawing, in one form ofconstruction by way of example, a vertical longitudinal section throughthe complete apparatus being shown.

A drum 1, which is fed with air through an aircooler 2, serves forreceiving the material to be treated, the air being preferably moistenedin this air-cooler by means of an air-moistening apparatus 3 which maybe shut off or thrown out of action, the air before entering the drum 1being passed through a water-separator 4, in which the surplus watercarried with the air in the form of drops is eliminated. Thiswaterseparator & consists of a pipe 5, which is perforated, andsurrounded by an enlarged casing 6 to catch the eliminated water, whichis then conveyed through a pipe 7 to an other casing 8 from whence itruns away through a further pipe 9 together with the water eliminated orprecipitated there. A. kind of helical surface 10 is provided foreliminating the water, and this surface eX- tends as far as the drum 1or to the pipe 11 and opposes the air current, so that the water isseparated from the latter; and further the air on its escape from thewaterseparator 4t and on its entrance into the drum 1 is distributedtherein. The waterseparator 4 is stationary and is packed Specificationof Letters Patent. Application filed January 12, 1912. Serial No.670,895.

IN MALTING- against the druinl by packing strips 12. Finally in order ifnecessary to be able to introduce water directly into the drum, a pipe13 may be provided which has suitable apertures inside the drum.

The air -moistening apparatus consists substantially of nozzles 3, towhich water is conveyed through pipes 14:. Removable covers 15 are alsoprovided to allow access to the nozzles 3, and after the removal ofthese covers the nozzles 3, for instance, may be adjusted.

The moistening of the air, the elimination of the water, and thedistribution of the air take place in the following way :The nozzles 3are adjusted according to requirements, and water is then conveyed tothem through the pipes 14: and also air from above forced into theair-cooler 2 by means of a fan, piston or the like. When the air hasbeen saturated with moisture, it escapes at the lower end of theair-cooler 2 into a jacket or casing 8, from whence it reaches thewater-separator 4. Here the moistened air encounters the helical surface10, whereupon the surplus water is precipitated and carried off througha pipe 7, while the air is at the same time distributed in consequenceof the helical form of the surfaces 10, so that it flows through thewhole of the drum 1.

While I have shown the drum as a malting drum, it will be understoodthat the apparatus could be used in connection with any receptacle inwhich it is desired to supply cooled and moistened air.

I declare that what I claim is 1. An apparatus for supplying areceptacle with air having moisture therein and for regulating saidmoisture, consisting of a moistening and cooling chamber, a secondhorizontal chamber in communication with a moistening chamber, a spiralbaffle located in the horizontal chamber, said horizontal chamber havingperforations in its walls, a casing surrounding the horizontal chamberaround the perforated portion, and a pipe leading from the casing to themoistening chamber. 7
